Renamed methods which are not setting up event listeners (from 'on' convention to more clear now 'anotherPlayer...')
WinBoard player is powered by possibility to set up a high-level listener to offer draw event from Winboard server
Moved logic of reaction to the draw offer to the caller.
Java path upgraded to the full. While it makes the command not portable, it ensures absence of error with registry entry of java7 (after installing java7 very often I get weird errors of version incompatibilities)
